1. 21. TV-tittande som dialog : På väg mot en symbolisk-interaktionistisk TV-teori

   Författare :Margareta Rönnberg; Stockholms universitet Institutionen för filmvetenskap; []
   Nyckelord :HUMANIORA; HUMANITIES; identification; para-social interaction; mirroring; symbolic interactionism; role-taking; the TV-other ; the generalized media-other ; dialogue; aesthetic philosphy; imagination; narrative psychology; identity construction; values; evaluation;

   Sammanfattning : Research itself -  on television and the young -  is the object of this research. From a humanistic viewpoint, relational and interactional concepts are critically scrutinized: how have eg 'identification' and 'para-social interaction' been defined and used by (psycho-analytically influenced) mass communication researchers in sociology, psychology and pedagogy in order to allegedly 'explain' the 'effects' of television on the identity, personality or behavior of young viewers? These definitions and uses are found lacking in many respects, and the views of insightful film theoreticians are recommended instead. LÄS MER

3. 22. Materials Based on Protein Nanofibrils

   Författare :Xinchen Ye; Mikael S. Hedenqvist; Christofer Lendel; Richard T. Olsson; Jonny Blaker; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein nanofibrils; whey protein; hydrogel; film; microfibre; protein structure; mechanical properties;

   Sammanfattning : Protein nanofibrils (PNFs) prepared from whey protein isolate (WPI) at low pH and elevated temperature were processed into materials, i.e. hydrogels, films, foams, and fibres, for different applications where they could potentially be sustainable alternatives to petroleum-based polymers.

5. 24. Advances in Thermal Insulation : Vacuum Insulation Panels and Thermal Efficiency to Reduce Energy Usage in Buildings

   Författare :Thomas Thorsell; Folke Björk; Mark Bomberg; Targo Kalamees; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vacuum insulation panels; VIP; serpentine edge; thermal bridge; composite film; gas diffusion; defect dominated; holistic approach; building enclosure; integrated testing and modeling; energy equivalent; field performance; air flow; thermal insulation efficiency;

   Sammanfattning : We are coming to realize that there is an urgent need to reduce energy usage in buildings and it has to be done in a sustainable way. This thesis focuses on the performance of the building envelope; more precisely thermal performance of walls and super insulation material in the form of vacuum insulation. LÄS MER

7. 25. An Experimental Study on Micro-Hydrodynamics of Evaporating/Boiling Liquid Film

   Författare :Shengjie Gong; Ma Weimin; Horst-Michael Prasser; KTH; []
   Nyckelord :liquid film; critical thickness; boiling; critical heat flux; rupture; dry spot; confocal optical sensor; SRA - Energy; SRA - Energi;

   Sammanfattning : Study of liquid film dynamics is of significant importance to the understanding and control of various industrial processes that involve spray cooling (condensation), heating (boiling), coating, cleaning and lubrication. For instance, the critical heat flux (CHF) of boiling heat transfer is one of the key parameters ensuring the efficiency and safety of nuclear power plants under both operational and accident conditions, which occurs as the liquid layers (microlayer and macrolayer) near the heater wall lose their integrity.
